Its an episode where they are in this hotel working under cover and they somehow end up "doing it". The only thing i remember is McGee pretending to be a hotel worker, bringing food to the hotel room which tony and ziva is in. Then in the morning they pretend to "do it" (in order to fool the people that are spying on them) ziva is laying down and tony is over her doing push ups so it looks like they are doing it. I also remember one of the people that are spying on them is an asian woman. Anyone that can name the season and episode, THANK YOU!
